Wisconsin State NFA Rules and Allowable NFA Items

Wisconsin's NFA laws, which can be quite confusing, are currently in a state of flux. There are virtually no restrictions on owning short-barreled rifles or short-barreled shotguns, and silencers may be possessed by “any person who has complied with the licensing and registration requirements under 26 USC 5801-5872” (the NFA); however, machine guns are essentially illegal without permission from the local chief law enforcement officer (police chief or county sheriff).
